To all whom it may concern: 7

Be it known that we, ROBERT W. ASHLEY and FRANK OBERKIRQH, citizens of the United States, and residents, respectively, of New York city, in the county of New. York and State of New York, and St.

Marys, Elk county, Pennsylvania, have invented new and useful improvements in De mountable Rims for Wire, "Wheels and the like, of which the following'is a specification.

The invention relates to improvements in demountable rims for Wire wheels and other vehicle Wheels utilizing pneumatic and solid tires for motor ears.

@ne object of the invention is the providinp,- of a fixed Wheel rim having formed therein means adapted to receive an auxiliary rim, and means adapted to receive a series or plurality of spokes strung under tension. between said fixed. rim and a suitable hub.

Another object of the invention is the providing of supporting ehannels "formed in the body of the fixed rim adapted to have punched therein suitable cups arranged to receive the spoke nipples of Wire spokes, the supporting; channels thereof providing; a means arranged to prevent the distortion of the telly band or rim. and of the injury of the tension of all of the spokes strung between said rim and a suitable hub.

Another and further object of tbe invention is the providing of detachable means forming part of tie fined rim, arranged to receive an auxiliary semi-flexible or rigid demountabie rim to which a pneumatic tire or other form of tire is attached and when not in use carried as a spare rim. constructing" the demountable rim which may be of semi-flexible nature, out of a e'om parativeiy thin cold rolled steel suitable auxiliary demountable rim is provided which when. placed upon the Wheel rim and the tire iniiated becomes substantially part of the Wheel rim structure as a Whoie, the detachable means as associated with the fixed rim providing a means of readily and quieirly demounting: the auxiliary rim from the rim structure and "fiirther by reason of its sene'i-fienibili the inereased inflation oi togetiwr wit nrai.

Channel 3 has mounted therein dr able side flange 9 iorn'iingr the opposi 1 rim flange and is arranged. together with flange '2 to (engage the side flung it) of anniliary send-flexible or flexible d nonntable rim llhaving mounted thereon a pneumatic tire casing or shoe l2 which has in turn mounted therein a sutiable tube of the stand ard type 13.

Said rim .i i v tnereol 11 is split transverseiy on a diagonal plane at one place in its cumference at and said flanges id have out therein apertures 15 to e suitable rim breaking tool for demounting said rim 11 from a pneumatic tire.

A, suitable valve stem aperture 16 is.

l. A device of the character described a fixed rim provided with tire comprising and spoke reception means and a channel adapted to receive a detachable retaining ring, and a removable tire supporting rim adapted to engage said fixed rim and sai detachable retaining ring, said removable rim being sufficiently rigid to support a semi-inflated tire under normal conditions and smaller in contour than the reception sur' ace on said fixed rim, and of sufficient flexibility to permit of its spreading and locking itself in said under full inflation thereon.

A device of the character described comprising a fixed rim having formed therewith the reception means, and a detachable sidering reception means, a detachable ring mounted therein, and a dem untable tire supporting rim ar'ranged to engage said fixed rim and cicnt rigidity to support a semi-inflated tire thereon, and being sufliciently smaller in contour as to seat itself on said fixed rim between the retaining means thereon when in normal condition, yet being sufficiently flexible as to spread transversely thereof and seat and lock itself on said fixed rim when said tire is inflated.

In witness whereof we have hereunto signed our names'in'the presence of two subscribing witnesses. I
